I inhaled mold and i'm curious if mold spores can cause damage to my lungs if i inhale daily. Can immune system handle it or i will get infection ?

I inhaled mold and i'm curious if mold spores can cause damage to my lungs if i inhale daily. Can immune system handle it or i will get infection ?

Depends: Mold spores are in the air everywhere. It depends on what type of mold, how much and if you have any existing lung disorder. A normal immune system can usually handle mold spores, but allergic reactions may occur with normal immune system. If you have any respiratory symptoms, it would be prudent to see your doctor. For good health - Have a diet rich in fresh vegetables, fruits, whole grains, low fat milk and milk products, nuts, beans, legumes, lentils and small amounts of lean meats. Avoid saturated fats. Exercise at least 150 minutes/week and increase the intensity of exercise gradually. Do not use tobacco, alcohol, weed or street drugs in any form. Practice safe sex. ...Read more
